摘要

An in depth industrial hygiene survey was conducted at the Micro-Biotrol Company (SIC-2099), Chicago, Illinois, to assess the extent of ethylene-oxide (75218) (Et0) exposure for workers. Micro-Biotrol is engaged in the contract treatment of spices and mixtures, including sterilization with Et0. Average Et0 exposure levels ranged from less than 0.11 parts per million (ppm) to 4.03ppm during September, and increased to 12.13ppm during January with vessel operators experiencing the highest exposures. Short term exposure monitoring also depicted the potential for extremely high peak exposures of 6.9ppm to 444.8ppm. These exposure levels are all above OSHA and NIOSH standards. Although vessel operators wore air purifying respirators during some procedures, other personnel in the general area were not protected. No respirators were provided at the facility prior to 1984. The authors recommend that the company conduct personal exposure monitoring for Et0 to assure exposure levels are below the standards.
